Summary: Different eco-friendly processes were studied to treat olive mill wastewater for the European 2024 zero-waste plan. The application of advanced oxidation processes, flocculation, and filtration proved to be effective in obtaining high-quality regenerated water. However, the increase in total iron content resulted in toxicity, which was resolved through subsequent flocculation and filtration steps. The optimized process achieved regenerated water suitable for irrigation with improved quality parameters.

Summary: One negative aspect of landfilling is the production of multicomponent dark liquids containing various chemical pollutants. Effective treatment methods like UV/Fe2+/H2O2 and UV/Fe2+/S2O82- processes are evaluated for degradation of landfill leachate. Factors such as [Fe2+]/[Oxidant] ratio, UV light, dosing mode, and pretreatment by a physicochemical process are examined for their influence. Best removal efficiencies for COD, TOC, and color index are achieved under specific operating conditions, with UV/Fe2+/S2O82- process showing better performance despite the influence of sulfate radical selectivity.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes. Quantitative structure-activity relationship analysis showed that deactivating groups in the para-position enhance the process.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.
